Specification forming part of Letters Patent No. 165,755, dated July 20,1875; application filed February 11, 1875.

ence being had to the accompanying drawings, which form part of thisspecification.

My invention relates to an improvement in' earlamps; and consists in theconstruction of parts by which the glass chimneys generally used onlamps in which coal-oil or other volatile fluids are burned, aredispensed with,

and the smoke consumed or driven off, so as not to cause anyinconvenience, or to obscure the light, as will be more fully describedhere after.

The accompanying drawing represents my invention.

A represents the frame of a triangular form, the apex of which is cutoff or flattened, and in the upper part of this is placed apla-no-convexlens or bulls-eye, O. On the top of this triangular frame is a roof, E,elevated in the center, over which a chimney, 19, is placed. The innerside of the frame A is closed by a glass door, a, hinged at its upperedge to the frame A, so that the door has to be lifted up to gain accessto the interior. In the center of the bottom within the frame A is anopening, 0, which communicates with the outside by means of the air tube(1 under the bottom of the frame, which tube is made considerably largerthan the opening 0, so as to occasion a stronger current of air. Avalve, m, closes 'or opens the opening 0 by means of a rod, f, curved atits outer end, so as to serve the double purpose of operating the valve,and of fastening or unfastening the door a, and is applied so that thedoor is fastened down by turning the catch g, or the rod f, the valve isopened, and, vice versa, shut when the glass door is opened. Thisarrangement is to prevent a counter current of air, by which the flamemight be extinguished when the frame is opened. The lamp B has anopening, h, in the bottom, into which, when placed over the opening 0,the air rushes. throughthe air-tube d, and passes through the tube "6 inthe interior of the lamp,

and through the perforated plate 1 into and around flame, which isconfined by a domeshaped covering, 0, over the plate I, and issuesthrough a narrow slit in this cover.

The object of this invention is to dispense with the glass chimneysnecessary to supply the required current of air for a perfect combustionof smoke. By introducing this current of air from the outside into andaround the flame in greater quantities, as is done by this invention,the frame A supplies the place of the glass chimneys, the smoke isconsumed, and all the incombustible parts carried away through the tube19 on the top of the roof of the frame. At a short distance from theroof the tube 19 is surrounded by a jacket, T, which is wider at itsupper than its lower end, and diverges into two short descending tubes,.9, at opposite sides. Around the lower edge of the jacket is a plate,5, as wide as the frame A, and nearly as long, and slightlybentdownward. This arrangement prevents the currents of air caused bythe opening of the cardoors from interfering with the flame in the lamp.

Having thus described my invention, 1 claim l. The frame A, having theair-tube d, in

combination with a lamp having one or more air-tubes passing through it,substantially as described.

2. In combination with the door a, the rod f, having the valve m securedto its inner end, and a catch on its outer end, whereby the valve isopened when the door is locked, and closed when the door is opened,substantially as set forth.

3. In a lamp for street-cars, the combination of the air-tubes i,perforated plate I, and covering 0, substantially as shown.

4. In combination with a lamp for streetcars, the tube 1), jacket 1,tubes 8, and plate 5, whereby the flame is prevented from beingextinguished by currents of air, substantially as described.

In testimony that I claim the foregoing, I have hereunto set my handthis 4th day of February, 1875.

FRANK RHIND.
